resume-optimization

resume-optimization is a skill for Claude Code, Codex from zszz3/AgentRecall. It costs 45 tokens per session (1,796 once invoked), scanned A, original, MIT.

Guidance for improving software-engineering resumes, including achievement bullets, job-specific wording, structure, and ATS matching. An ATS is software employers use to scan resumes for relevant terms.

In plain words
What is it for?
Use it to review a resume, write quantified accomplishment bullets, extract keywords from a job description, or tailor a resume to a role.
Why use it?

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

resume-optimization scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 6d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Resume Optimization

Comprehensive guidance for creating effective software engineering resumes that pass ATS systems and resonate with hiring managers.

When to Use This Skill

  • Reviewing or improving a software engineer's resume
  • Crafting impactful achievement bullets from work experience
  • Optimizing resume content for ATS keyword matching
  • Tailoring a resume for a specific job description
  • Understanding modern resume structure and formatting

Core Principles

The Resume's Purpose

A resume is a marketing document, not a job history. Its purpose is to:

  1. Pass ATS screening (keyword matching)
  2. Capture a recruiter's attention (6-second scan)
  3. Demonstrate value through quantified achievements
  4. Secure an interview opportunity

What Makes Engineering Resumes Different

Software engineering resumes should emphasize:

  • Technical impact: Specific technologies, scale, and performance improvements
  • Business outcomes: Revenue, cost savings, user growth, time savings
  • Leadership signals: Mentoring, cross-team collaboration, technical decisions
  • Quantification: Numbers that demonstrate scope and impact

Resume Structure Quick Reference

Recommended Section Order

  1. Contact Information - Name, email, phone, LinkedIn, GitHub (optional)
  2. Professional Summary (optional) - 2-3 sentences for senior roles
  3. Skills - Technical skills organized by category
  4. Experience - Reverse chronological, 3-5 most relevant roles
  5. Projects (optional) - For junior engineers or career changers
  6. Education - Degrees, certifications, relevant coursework

Length Guidelines

Experience Level Recommended Length
0-5 years 1 page
5-10 years 1-2 pages
10+ years 2 pages max

Formatting Essentials

  • Font: Clean, readable (Calibri, Arial, Garamond - 10-12pt)
  • Margins: 0.5-1 inch
  • Format: PDF (preserves formatting)
  • File naming: FirstName_LastName_Resume.pdf

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
